The SoSSI peripheral supports the MeSSI display interface standard. This
module includes a VIA-bus interface converted into a TIPB interface
connected on the MPU shared peripheral bus and an interface with the system
DMA, which enables connection of an extended LCD display to the
OMAP5912 device.
The display interface is a parallel interface. It consists of a display data I/O bus
(DispDataOut[15:0]), write enable (WRX), read enable (RDX), chip-select
(CS), and command/pixel data (A0) signals.

There are two instances of the MMC/SDIO module in OMAP5912. This
module is a superset of the MMC/SD module from OMAP5910, including I/O
interfacing capability to support an SDIO card.
The MMC/SDIO1 replaces the MMC/SD from OMAP5910, whereas the
MMC/SDIO2 is an additional peripheral.
The MMC/SDIO host controller provides an interface between a local host,
such as the MPU/DSP and MMC/SD/SDIO memory cards plus up to four serial
flash cards, and handles MMC/SDIO or SPI transactions with minimum local
host intervention.
